Runaway Reaction & Explosion

This is a (exo-)thermal explosion during a chemical process operation such as a batch, semi-batch or continous reactor process, but also possibly during drying, storage, distillation, evaporation, etc. Often part of the substance deflagrates initated by the thermal run-away. Also this phenomenon will often be associated with hot expanding gases fragmenting containment causing a blast, penetration and fire damage. In some cases a violent secondary vapor cloud explosion occurs after mixing of hot gaseous reaction products with air.
